A British researcher reports that the male ego is often larger than his actual IQ

Are men smarter than women? No. But they sure think they are. An analysis of some 30 studies by British researcher Adrian Furnham, a professor of psychology at University College London, shows that men and women are fairly equal overall in terms of IQ. But women, it seems, underestimate their own candlepower (and that of women in general), while men overestimate theirs.

Universally, men tend to score higher on certain specialized skills, such as spatial awareness. In the real world, that means they might be better at reading maps or navigating. Women score higher in terms of language development and emotional intelligence

There certainly is a greater male ego. It's what we call the male hubris and female humility effect

Surprisingly, [both] men and women perceive men being smarter across generations
